In Japan it is believed that women born in a hinoeuma year, the year of the Fire Horse in the fifth lunar calendar cycle, or every 60 years, are evil.
These women are considered dangerous and in league with spirits that are considered less than friendly. A woman born in a hinoeuma year would not make a good wife and thus men would avoid them at all costs.
The last hinoeuma year was in 1966 and resulted in a huge spate of abortions across Japan - lest the child be a female.
Records show that Japan had a sharp decrease in birth rates in 1966 which is generally attributed to this superstition based on the old lunar calendar.
